'ro ALL WHoM IT MAY ooNoEnN;

Beit known that I, J. T. lVARREN, of Stafford, in the county of Genesee,and State of New York, have invented certain new and useful improvementsin Sad-Irons; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making a portion of this specification. in whichiFigure 1 is a partial vertical longitudinal section ot' a sad-ironconstructed according to my invention.

Figure 2 is a vertical transverse section of thesame taken in the line x.'12 of iig. l.

Figure 3 is a horizontal section of the same taken in the line z z offigs. l and 2.'

This invention consists in the combination of an adjustable heating plugwith the hollow shell of a sadiron, in such manner that by placing thesaid plug at a greater or less distance from the bottom of the shell ithe heat imparted to the smoothing or ironing surface of the latter maybe graduated to any required degree, and whereby the plug may be mademuch hotter than in the smoothing irons hitherto devised, thus enablingthe P iron to be used for a proportionally greater length of timewithout reheating. The invention further consists in a novel meanswhereby the facile and convenient adjustment of the heating plug issecured.

To enable-others to understand the nature and construction of myinvention, I will proceed to describe it with reference to the drawings.

The hollow shell A is made of any suitable form, and its iiat under sideor surface constitutes the smoothing or ironing surface of the iron. Thehorizontal handle B is situated longitudinally at a suitable distanceabove the shell A, and is attached thereto by means of suitable uprightbraces a. One end of the aforesaid handle projects beyond the braces a,adjacent to the said end, and has passed vertically through it athumb-screw, b, the lower portion of which projects downward below theaforesaid end of the handle B, and which operates in the verticaladjustment of the heating plug, as will be hereinafter fully explained.This plug is shown at C, and consists of a' block of iron or othersuitable metal of' any appropriate thickness. and ofa shapecorresponding to that of the interior of the shell A. Formed in theupper side of the plug Ulis a recess, c, furnished with a smalltransverse bar, d, which enables the plug to be removed from or placedin theshell A by means of a separate or detachable hook or handle orother proper instrument. D indicates the supporting frame which sustainsthe plug C, and which is composed of a bent rod, the horizontal portion,b', of which.is situated longitudinally within the shell A, and isfurnished at one end with a transverse horizontal piece, 1) Thishorizontal portion of the frame D is fitted into grooves ofcorresponding shape, formed in the under side of the plug C, which isplaced upon and supported by the aforesaid portion. That portion of therod constituting the aforesaid frame opposite the end upon which thecross-piece b is formed, is turned upward into a vertical position, andis provided at its upper end with a head or outwardly projecting knob,a', which is provided with a female screw, into which is screwed thelower portion of the thumb-screw b in such manner that, by turning thesaid thumb-screw in one direction or the other, the fra-ine D, andconsequently the plug C, may be raised or lowered as desired. The plug Cbeing first made hot is placed in the shell A, and resting upon thehorizontal portion of the frame D, and is raised or lowered by means ofthe thumb-screw b, as just herein set forth, to a greater or lessdistance from the bottom ofthe shell, according as it is desired tocommunicate a greater or less degree of heat thereto. Thus, forinstance, if a comparatively high heating of the aforesaid bottom isdesired, the plug is placed nearly or quite in contact therewith, but inease it is desirable to have it heated to a lower degree, the plug israised upward to a suitable distance thereform, so that by these meansthe heat communicated to the smoothing surface of the iron, or, in otherwords, the temperature of the bottom of the shell, may be graduated toany degree required, at the same time that, inasmuch as the plug may bemade much hotter than would be admissible if it were intended to beplaced permanently upon the bottom of the shell, it follows that thebottom ofI the iron may be kept properly heated for a proportionatelygreater length of time without rohen-ting the plug. If desired, a guard,Eformed of any suitable material, may be interposed between the handle Band the plug C, with its ends attached to the braces a for the purposeof protecting the handv of the operator in using the iron from the heatradiated from the plug.

What I claim as new, and desire tosecure by Letters Patent, is

1. The combination of theadjustablemheating plug C, with the hollowshell A, whereby the smoothing surface of the said shell may be heatedto a greater or less degree by adjusting the plug at a greater or lessdistance from the bottom ofthe aforesaid shell, substantially as hereinsetforth.

2. The thumb-screw l), and supporting frame D, combined relation witheach other, and with the handle B, heating plug C, and shell A,substantially as herein set 'forth `for the purpose specied.
